Abstract:
A temperature adjustment control device includes a heat diffusion layer, a heat flux sensor, and a temperature changing body provided in this order from a surface making contact with a human body. The heat flux sensor is disposed on the temperature changing body and outputs a sensor signal corresponding to a heat flux. The heat diffusion layer is disposed opposite to the temperature changing body through the heat flux sensor. The heat flux sensor outputs the sensor signal corresponding to the heat flux passing through the heat flux sensor in a direction in which the heat diffusion layer, the heat flux sensor, and the temperature changing body are arranged. A control portion controls a start and a stop of the power supply to the temperature changing body based on the sensor signal outputted from the heat flux sensor.
Abstract:
A liquid level detector includes: a detecting element having one surface and the other surface opposite to the one surface, the one surface being opposed to a liquid, while being parallel to a height direction of liquid level; a Peltier element provided on the other surface side of the detecting element; and a control unit performing a detection processing for a liquid level of the liquid. The Peltier element forms a heat flow passing through the detecting element from the other surface to the one surface, toward the liquid or a gas. The control unit calculates a liquid level on the basis of an output value of an electrical signal outputted according to the heat flow passing through the detecting element, and a relationship between an output value of the detecting element and a liquid level.

A non-contact power supply control system includes: an electric transmission pad connected to a power source unit; a control unit controlling current supply to the electric transmission pad; a living body detecting means detecting a living body present around the electric transmission pad; a power receiving pad magnetically coupled to the electric transmission pad to excite power, when current is supplied from the power source unit to the electric transmission pad; and a power storage unit storing power excited by the power receiving pad. The living body detecting means are arranged on the road surface side, and the control unit, when determining that no living body is present around the electric transmission pad on the basis of a result from the living body detecting means, controls the power supply unit to supply power to the power storage unit.
Abstract:
An abnormality diagnostic apparatus includes: a heat flux sensor that detects heat flux generated by a measurement target continuously from the start of operation of the measurement target or at predetermined time intervals; and a control device that determines whether there is an abnormality based on the result of the detection by the heat flux sensor. In the event of an abnormality in a facility, heat flux generated from the facility by at least one of current, voltage, sound, vibration, and friction changes. Therefore, the use of the heat flux sensor makes it possible to determine the presence or absence of an abnormality in the measurement target without using a plurality of kinds of sensors to measure current, voltage, sound, vibration, and friction.
Abstract:
A heat flux sensor is installed in such a way that heat flux emanating from a biological object present at a predetermined position is detectable. It is determined whether or not a biological object is present at the predetermined position by comparing sensing results of the heat flux sensor with determination criteria. The determination criteria is preset according to heat flux that can be sensed when a biological object is present at the predetermined position. When the sensing results of the heat flux sensor satisfy the determination criteria, in other words, when the heat flux sensed by the heat flux sensor is the heat flux emanating from a biological object, it is determined that a biological object is present at the predetermined position. Consequently, it is possible to realize accurate detection of a biological object.
Abstract:
A heat quantity control device has a heat flux sensor arranged between first and second heating elements arranged adjacently to each other, and a control section for controlling a heat quantity of the first and second heating elements. The heat flux sensor has an insulation board made of thermoplastic resin, first and second via holes formed in the insulation board penetrating in a thickness direction thereof. First and second layer connection members are embedded in the first and second via holes, respectively. The first and second layer connection members are made of different metals and alternately connected in series. The control section controls a heat quantity generated in the first and second heating elements based on the electromotive force generated in the heat flux sensors so that a heat flux flowing between the first and second heating elements becomes not more than a predetermined value.
